Cohere is hiring a senior research scientist for model evaluation. The work covers designing new benchmarks that test what large language models can do, researching evaluation methods — training LLM judges, refining data synthesis pipelines, improving evaluation efficiency — and building reusable tools to examine model performance. The posting asks for strong software engineering skills, fast prototyping with LLMs, and substantial time spent reviewing complex data and model outputs for quality. Cohere lists the role as hybrid across several locations, and allows a fully remote base with no minimum in-office days.
